K+and Li ions were removed by treating the KTLO crystals (1.0 g) with 100 ml of a 1 M HCl solution for 3 days at room temperature.
Webcatalytic properties of isostructural layered compounds with various cation compositions [19]. In this paper we present results of studying some perovskite-type layered titanates A2Ln2Ti3O10 (A = Li, Na, K; Ln = La, Nd): the stability of these compounds in water and in a damp atmosphere, their ability to intercalate water in WebTools. In materials science, the term single-layer materials or 2D materials refers to crystalline solids consisting of a single layer of atoms. These materials are promising for some applications but remain the focus of research. Single-layer materials derived from single elements generally carry the -ene suffix in their names, e.g. graphene.
